(莴苣)

    有个坐监的犯人,一天收到妻子的来信:"亲爱的丈夫, 我想在后园种些莴苣, 什么时候是最佳时间呢?" 犯人知道狱警会检查所有的信件往来,于是他写道: "亲爱的妻子,你做什么也不要动后园,那是我藏钱的地方." 大约过了一个星期, 他又接到了妻子的来信: "亲爱的丈夫,你一定想象不到, 有几个人带着铲来到我家, 把后园翻了个底朝天." 犯人回信: "亲爱的妻子,现在就是种莴苣的最佳时机了."

A prisoner in jail receives a letter from his wife: "Dear Husband, I have decided to plant some lettuce in the back garden. When is the best time to plant them?" The prisoner, knowing that the prison guards read all mail, replied in a letter: "Dear Wife, whatever you do, do not touch the back garden. That is where I hid all the money." A week or so later, he received another letter from his wife: "Dear Husband, You wouldn't believe what happened, some men came with shovels to the house, and dug up all the back garden." The prisoner wrote another letter back: "Dear wife, now is the best time to plant the lettuce."
